Job Description
PV TECH 3 – Senior
Role Summary
Attached to the head office, the PV technician works alone or in a team on our customers' solar installations. As part of a team experienced in photovoltaics, he participates in the operation and ensures preventive and corrective maintenance visits of all equipment and systems of the sites in a safe, reliable, efficient, environmentally friendly, and safety-compliant manner. The technician intervenes in accordance with the company's values: Responsibility, Discipline, Commitment, Responsiveness, Sobriety, Curiosity. Domiciled at one of our bases in France, he works on all types of photovoltaic installations (roof, carport, ground-mounted power plant – fixed and tracker or agricultural greenhouse). Attached to his area, he intervenes within a 2-hour radius daily but also occasionally in the rest of France.
Evolution compared to level 2:
The Senior PV Technician is an autonomous field expert, capable of managing complex interventions, including HVA. He regularly supervises work-study and junior students, supervises construction sites and acts as a technical interface with customers. He also intervenes independently on routine maintenance operations of storage systems (BESS) and participates in the diagnosis of simple to medium failures.
- Evolution from Level 2 (Advanced)
- Transition from limited autonomy to full autonomy on simple/medium LV and HVA interventions.
- Advanced LV fault diagnosis, HVA diagnostics.
- Site management (heavy maintenance, retrofit, module replacements).
- Simple to medium diagnostics on BESS (battery modules, DC wiring, PCS).
- Intermediate understanding of BMS/EMS operation and ability to analyze monitoring data.

Essential Duties & Responsibilities:
- Preventive maintenance
- Carry out LV and HVA preventive maintenance independently (visual inspections, thermography, tests, manoeuvres, measurements).
- Carry out preventive maintenance on BESS independently (visual inspection, wiring control, simple tests, monitoring of the status of the modules).
- Corrective maintenance
- Perform complex corrective interventions in LV (measurements, IV curve, HT-instrument, etc.).
- Carry out simple to medium corrective interventions in HTA (DEIE, GTE, backup, centralized inverters).
- Commissioning of LV installations and monitoring systems independently.
- Carry out routine corrective maintenance on BESS (replacement of components, DC wiring check, PCS) independently.
- Analyze data from the BMS/EMS and identify operating anomalies.
- Carrying out electroluminescence inspections with analysis.
- Site management
- Prepare and manage maintenance sites (massive replacements, retrofits).
- Coordinate multiple tasks and projects simultaneously.
- Supervision
- Supervise work-study students, juniors and temporary workers on site.
- Train experienced technicians on first-level BESS interventions
- Play the role of safety referent on site.
- Customer Support & Relationship
- Participation in operations, material ordering and planning operations
- Participate in the simple commissioning of BESS systems (basic tests, parameter validation).
- Write detailed technical reports.
- Communicate directly with customers on technical aspects.
- Compliance & Security
- Guarantee the safety of interventions within its perimeter, in line with internal rules and those of customers.
- Apply and enforce specific BESS procedures (HVDC, fire, thermal).
- Compliance with contractual commitments (deadlines, availability).
- Monitoring of interventions in the CMMS.
- Participation in weekend on-call duty
